Understanding infectious diseases such as influenza is an important element of health literacy. We present a fully validated knowledge instrument called the Assessment of Knowledge of Influenza (AKI) and use it to evaluate knowledge of influenza, with a focus on misconceptions, in Midwestern United States high-school students. A two-phase validation process was used. In phase 1, an initial factor structure was calculated based on 205 students of grades 9–12 at a rural school. In phase 2, one- and two-dimensional factor structures were analyzed from the perspectives of classical test theory and the Rasch model using structural equation modeling and principal components analysis (PCA) on Rasch residuals, respectively. Rasch knowledge measures were calculated for 410 students from 6 school districts in the Midwest, and misconceptions were verified through the χ 2 test. Eight items measured knowledge of flu transmission, and seven measured knowledge of flu management. While alpha reliability measures for the subscales were acceptable, Rasch person reliability measures and PCA on residuals advocated for a single-factor scale. Four misconceptions were found, which have not been previously documented in high-school students. The AKI is the first validated influenza knowledge assessment, and can be used by schools and health agencies to provide a quantitative measure of impact of interventions aimed at increasing understanding of influenza. This study also adds significantly to the literature on misconceptions about influenza in high-school students, a necessary step toward strategic development of educational interventions for these students. 相似文献

Despite possible negative effects, many children do not tell their teachers when they have been bullied. This study examined junior school pupils' (N = 294) reports of instrumental, emotional and validation social support received after disclosing being bullied to teachers, and associations with intentions to disclose in the future. Overall, participants reported receiving modest to high levels of social support. The three social support variables accounted for a significant proportion (16.3%) of the variance in intentions to disclose. Each of them also emerged as significant non unique predictors (i.e. not controlling for their shared variance), and validation social support did so even after controlling for the influence of the other two types. These effects were stronger for boys than for girls, and some varied by age. Findings are discussed in terms of outcome‐ expectancy theory and practical implications. 相似文献

Assumption of the burden: Science or criticism? 总被引:1,自引:0,他引:1
This article adjudicates the claim to science made by current researchers in speech communication. It argues the point that contemporary research is best characterized as criticism, and that the cause of research in the field would be best advanced if scholars engaged in the enterprise of discourse analysis and conversation analysis regarded themselves as critics and made themselves subject to criticism as such. 相似文献

In British Columbia, Canada, two population‐based databases have been linked at the level of the individual child: the Early Development Instrument, a Kindergarten school readiness measure; and the Foundation Skills Assessment, a Grade Four academic assessment. Utilising these linked data, we explored the early school readiness, literacy, and numeracy outcomes of a province‐wide study population of children with special needs (N = 3677) followed longitudinally from Kindergarten to Grade Four. In particular, we explored the categories of special needs among our study population. In addition, we investigated the Kindergarten school readiness and Grade Four literacy and numeracy outcomes of children with special needs. We also explored the Grade Four literacy and numeracy outcomes of children with special needs who were ‘not school ready’ at Kindergarten. Finally, we identified the categories of special needs of children who participated in the Kindergarten data collection, but were missing literacy and numeracy scores at Grade Four. Future directions are discussed. 相似文献

Gatekeeping in counselor education is an ethical responsibility and professional best practice. The authors examined gatekeeping perceptions of 9 counselor educators, with equal representation of assistant professors, associate/full professors, and adjuncts/instructors/lecturers. The authors analyzed data using consensual qualitative research methodology (Hill, Thompson, & Williams, 1997 ). Findings include commonalities and differences between academic role groups. 相似文献

This article applies Goldratt's thinking process (TP) to problems associated with an engineering consulting firm's invoicing system and the need to increase productivity to maintain demand. The core problem found was the company was not maximizing the use of project management personnel. Results of the TP are an effect‐cause‐effect analysis that considers undesirable effects associated with increasing productivity. By identifying the core problem, we determined what to change, what to change to, and how to cause the change. 相似文献

Curves are included showing the relationship between voltage and relative position of electrodes, and between voltage and counter gas pressure. Also included are experiments on the preparation of sensitive and insensitive points, and experiments with different electrode materials. These data are for a counter operated with the point at negative potential.Zeleny's conclusion that a high resistance layer of adsorbed gas exists at the point is adopted. In addition, the assumption is made that the field at the point at the onset of “self-counting” is sufficient to produce auto-electronic emission. This combination now leads to a theory which accounts for the various characteristics of the counter and explains the threshold of counting curve, the auto-counting curve, and the continuous discharge curve. Probability considerations account for the selective counting of different ionizing agents in certain voltage ranges, for the dependence of counting upon path of ionizing rays through the chamber, and for the increase of counts with increase of voltage from threshold of counting to the point where all rays are registered. 相似文献
